GraphHopper is a fast, memory-efficient routing engine for developers building navigation, route planning, and geospatial applications.
It can be used as a Java library or deployed as a standalone web server, using OpenStreetMap data by default to calculate routes, travel times, turn-by-turn instructions, and road attributes. It also supports map matching, isochrone calculation, and public transit routing with GTFS data.
This is free and open source software.
Key Features
- Works with OpenStreetMap data and can be adapted to custom data sources.
- Includes pre-built routing profiles for car, bike, mountain bike, foot, hike, truck, bus, and motorcycle.
- Provides a web API together with Java and JavaScript client support.
- Supports map matching for snapping traces to roads.
- Offers turn instructions in more than 45 languages.
- Handles elevation data, turn costs, turn restrictions, country-specific rules, and custom routing areas.
- Scales from small indoor-sized graphs to world-wide-sized routing graphs.
